<u>Answer:</u>
A. a lot of travel is not typically required for a farmer; similarly, a lot of traveling for work is not generally required of veterinarians.
C. Veterinarians and farmers both work with animals, although in different ways.
D. Job opportunities for farmers are declining, while job opportunities for veterinarians are rising.
<u>Explanation:</u>
In a <u>Venn diagram</u>, two circles denote two sets of information, with different characteristics. Their area of intersection, however, represents the qualities that they both share, or their common grounds.
Based on this it can be said that the farmers and veterinarians share two common grounds - "work and care for animals" and "very little travel involved." The latter makes option A correct.
The correctness of option C (Veterinarians and farmers both work with animals, although in different ways) is because of two reasons: according to the Venn diagram, they both share "work and care for animals," but, each of them also have different characteristics of work mentioned as "produce crops and dairy products" for the farmers and "often work in private clinics" for the veterinarians, which also makes their work different.
It can be seen from the uncommon zones of the circles that for the farmers, the job opportunities are declining, while they are rising in case of the veterinarians, which proves the correctness of option D.
